Background and aims A major challenge in root exudation research is obtaining exudates samples that accurately reflect the exudation processes under natural soil growth conditions. Both growth environment and experimental setup can significantly influence root exudation dynamics. This study investigated how different experimental systems and growth conditions affect carbon exudation in maize ( Zea mays L.) roots and whether these factors could influence the detection of genotypic differences between the wild type (B73) and its hairless mutant, rth3. Methods Maize plants were grown under various experimental conditions, including soil-based and hydroponic systems. Root exudates were collected using a combination of traditional and innovative sampling approaches. Carbon exudation rates were compared across experimental setups and genotypes. Laboratory results were further compared with data from a separate field experiment. Results Exudation rates obtained from soil-based laboratory experiments were comparable to those observed in the field under similar growth temperatures. The contribution of root hairs to total carbon exudation was negligible compared to the effect of growth conditions and experimental setup. Large differences in root biomass introduced bias into exudation measurements, particularly when root to sampling volume ratio (RSVR) varied substantially. Conclusions Experimental setup and environmental conditions have a strong influence on root exudation measurement. Soil-based laboratory systems that closely replicate field conditions, particularly temperature, can serve as reliable proxies for field experiments, providing ecologically meaningful data. Maintaining a consistent RSVR is also essential for obtaining accurate and comparable results. These findings offer important methodological guidance for reliably quantifying root carbon exudation in maize

Background and aims Drought limits maize ( Zea mays L.) productivity worldwide. Microorganisms from hypersaline habitats possess traits that may mitigate water deficit through osmotic stress adaptations. We aimed to evaluate isolates from these environments as bioinputs for maize and to resolve whether their effects act via resistance (maintenance under stress) and/or resilience (recovery after rehydration). Methods We tested 65 bacterial and fungal isolates from rhizosphere sediments of halophytic plants in apicuns (hypersaline tidal flats) and salt flats. Maize was grown in non-sterile soil under greenhouse conditions with seed inoculation, irrigated initially, then exposed to progressive drought and rehydration. We measured SPAD chlorophyll index, leaf temperature, relative water content, proline, chlorophyll a, shoot dry mass, shoot-to-root ratio, and a drought visual score, and analyzed data with univariate contrasts and multivariate ordination. Results Several isolates improved performance relative to the droughted control. Resistance responses included maintenance of SPAD, moderated leaf temperature, and preserved relative water content. Resilience responses included recovery of SPAD and shoot growth after rehydration. The largest number of effective isolates belonged to Bacillaceae, notably Halobacillus and Virgibacillus . The most consistent response was observed for a Modicisalibacter isolate (Halomonadaceae), which combined thermal buffering, SPAD stability, enhanced root investment, and increased shoot biomass. Additional gains were observed with Halomonas and Aspergillus. Conclusions Hypersaline-derived microbes provide complementary functional strategies that differentially sustain maize during drought and recovery. Trait-guided screening offers a rational basis to design multi-strain inoculants targeting resistance and resilience phases under water-limited agriculture.
